CAR-ROOF.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed September 5, 1912. Serial No. 718,655.

which the following is a specification, reference being had to theaccompanying drawings. V

This invention relates to improvements in freight-car construction andparticularly in respect to the roofs of such cars.

The leading object of the invention is to so construct the roof membersthat several inches of additional space between the floor and the roofmay be had over the space now ordinarily obtainable, and withoutincreasing the height of the car-body or weakening the construction.This I accomplish by the construction and arrangement of parts shown inthe drawings and hereinafter specifically described.

That which I believe to be new will be set forth in the claims.

In the drawings,Figure 1 is a plan view, partly broken away, of acar-roof embodying my improvements; Fig. 2 is a side elevation, alsopartly broken away, of a car having my improvements embodied therein;Fig. 3 is a cross-section through a portion of the car and its roof;Fig. 4: is a detail being a vertical section taken at line 44 of Fig. 3;Fig. 5 is a detail being a plan view of a portion of the sheet-metalcovering that rests upon the purlins and the sub-carlines, and showingalso the cap over the sub-carline; Fig. 6 is a perspective view of oneof the metal roofingsheets; Fig. 7 is a detail being a vertical sectiontaken at line and Fig. 8 is a perspective view of a portion of theridge-pole of the carroof.

Referring to the several figures of the drawings in which correspondingparts are indicated by like reference numerals10 indicates the roofingboards or outer sheath ing; 11, one of the side walls of the car; 12 oneof the fascia boards; 13 the sub-purlins extending longitudinally of thecar and to which the rooting-boards 10 are nailed; 14 the sub-carlineswhich rest upon the main purlins. These main purlins are covered withthe metal sheets 15, the inner ends of which sheets are secured in slots16 in the side faces of the ridge-pole 17 as usual, and

the outer ends of which are turned down against the outer faces of theside walls 11. The side edges of the sheets extend over the sub-carlines1i and are covered by a cap .18, the inner ends of these sub-carlinesfitting, together with their coverings of metal sheets 15 and cap 18,into suitably shaped recesses in the side faces of the ridge-pole l7,oneof such recesses being shown in Fig. 8 and indicated by 19.

The parts so far mentioned with the exception of the main purlins are ofwellknown construction and need no further detailed description.

The main purlins are indicated by 20 and differ from the purlins in usein that in the lower face of each are formed a plurality of wide notches21, in which are adapted to be seated and secured the several maincarlines 22. These carlines 22 are of metal, and as best shown in Fig. 7are formed of inverted U or channel shape and of a size to closely fitwithin the notches 21 of the purlins. They are bent at their edgeportions to form outwardly-turned flanges 23 which lie against the underfaces of the purlins and through such flanges and through the purlinspass retaining bolts 24. The outer ends of the carlines rest upon theusual plates 24 at the sides of the car to which they are bolted by longbolts 25 passing through such plate and through the flanges 23, (seeFig. 3) and they are additionally braced and held in position at theirouter ends by brackets 26 bolted to the inner faces of the plates and tothe top' wall of the channel-shaped carline. That part of a bracket thatis secured to a carline is bestmade of a width to snugly fit between theside walls of the channel as thereby a more rigid union of the bracketand carline is secured.

The ridge-pole 17 is provided in its under face with notches 27corresponding in size and shape to the notches 21 in the purlins 20 andin alinement with the notches 21, so that the carlines are, at theircentral portions, received therein and secured by one or more suitablebolts 28.

By my construction I provide avery strong and rigid interlocking of thecarlines with the purlins and the ridge-pole as well as a very rigidlocking of the ends of the carline to the side plates, and at the sametime by insetting the carlines into the purlins and ridge-pole I gainadditional headroom in the car and thereby make it better adapted forreceiving large and bulky freight.

That I claim as my invention and desire to secure by Letters Patentis 1. In a car, the combination with a series of purlins each providedwith a plurality of notches in one of its faces, of carlines fitted insaid notches, said carlines having flanges resting against the faces ofthe purlins at each side of the notches, and means passing through saidflanges and through the unreduced part of the purlins for securing thepurlins and carlines together.

2. In a car, the combination with a series of purlins each provided witha plurality of notches in one ofits faces5 of channel-shaped carlinesfitted in said not-ches said carlines having turned edge portionsforming flanges that rest against the faces of the purlins at each sideof the notches, and means passing through said flanges and through theunreducedpart of the purlins for securing the purlins and carlinestogether.
